Types Of Mice: The 5 Most Common Mouse Species

Mice are common pests around the world. Although they are best described as small, fast, and furry, they aren’t all the same species. Today, we’re going to look at the most common mouse species and show you the different types of mice that you need to worry about. With this information in mind, you’ll know what species you’re most likely to run into.

Keep in mind that we are primarily concerned with the most common mice in the U.S., but we will talk about other places around the world, too. After all, some of the most common mouse species do overlap in areas around the world.

What Makes a Mouse?

Mice are small mammals that share a variety of characteristics. They are very small, sometimes just a few inches long, and they have relatively long tails, a snout that comes almost to a point, and small ears. Oftentimes, the most common mouse species measure between 4 and 7 inches and weigh between 0.4 and 3 ounces.

Mice are known for having a short gestation period and litters that range between 4 and 10 individuals. Mice are somewhat short-lived creatures , living between 2 and 7 years.

Also, mice belong to the order Rodentia , and they belong to several families, many genera, and many species . However, the animals called “true mice” belong to the family Muridae. It’s currently believed that there are over 1,000 species of mice across the world. Some of them are more common than others, and some of them are considered true mice and others are not.

How Are Mice Different from Rats?

Mice are distinct from rats even though the two share some common traits as rodents. However, one of the most frequent distinguishing factors for these animals is size. Rats have larger and heavier bodies than mice. Also, rats have longer and thicker tails than mice when compared to their overall size.

Rats have hairless and scaly tails but mice have thin and hairy tails in most cases.

It’s easy to tell these animals apart based on their choice of habitat, too. Rats tend to survive in urban areas , but mice tend to live in rural and suburban areas. Both prefer being close to humans , though. They enjoy the opportunity to steal food from human settlements.

As you can see, these are very different animals.

The Most Common Mouse Species: Types of Mice You’ll Find

Several species of mice exist in the world. We’re going to focus on the most common mouse species that you’re likely to find in the U.S.

Here’s a list of the 5 most common mouse species you’ll find. They are all notorious pests that are spotted in and around homes throughout the U.S. You need to watch out for them to ensure that your home is not infested.

5. Cotton Mouse

The Peromyscus gossypinus is known as the cotton mouse. This mouse is found in many places throughout the U.S., but it is most prominent in the southern states. The animal commonly stays in the woodlands, but it has no qualms about invading homes and garages.

This mouse is known for having a white stomach and feet along with brown fur on its topside and head. It actually looks like another member of this list, the white-footed mouse, but it’s larger in body size and skull. They average between 3.1 and 3.9 inches long, but closer to 7 inches when counting their tail length.

4. Western Harvest Mouse

As the name suggests, the western harvest mouse is primarily found in the western states in the U.S. However, its range includes states as far east as Indiana.  Like many other species, the western harvest mouse has brown fur and a white stomach. However, they also have a white stripe that runs down their sides along with a yellowish-buff color fur on the sides of their body.

These mice can measure anywhere between 4 and 5 inches, but a lot of that length comes from their tails.

3. White-footed Mouse

As you might imagine, it is easy to spot the white-footed mouse due to its light pink feet and white fur that surrounds them. The mouse is very widespread. It can be found in parts of Canada , all but the western coasts of the United States, and deep into Central America.

This mouse only weighs a little over an ounce, and it can grow anywhere up to 7 inches long including its tail. The white-footed mouse is very common, and it has been given many names. Among them is the woodmouse, a name that is common in the southern U.S. The mouse is notoriously short-lived in the northern parts of its habitat. This mouse only lives between 1 and 2 years in those areas.

2. Deer Mouse

The deer mouse goes by a few different names, but that’s to be expected of an animal with such a widespread distribution. They can be called the North American deer mouse or the eastern deer mouse. The deer mouse is found throughout Canada, the U.S., Mexico, and other parts of Central America.

They grow between 5 and 7 inches in length, and they are very hard to tell apart from the white-footed mouse. The deer mouse can be distinguished because it has a two-toned, brown-and-white tail. The deer mouse is frequently used in scientific studies, but it’s not quite as popular as the number one member on our list.

1. House Mouse

The Mus musculus or house mouse is probably the most common mouse species in the entire world. You can find the house mouse on every continent except Antarctica. These mice can measure between 5 and 8 inches including their tails and they weigh about an ounce and a half.

Aside from being one of the most common mouse species, they’re also one of the most significant. They are the model organism used in laboratory studies for a variety of scientific disciplines.

In the wild, they are found occupying homes and areas near them. They live in fields and farmlands, and they’re always looking for food. This species is commonly kept as a pet and it’s also one of the most common types of pests. In fact, they were originally from Europe and spread across the world due to exploration and colonization.

Now that we’ve looked at the various types of mice and the most common mouse species, you should have a pretty good idea of what mice are most likely to live near you. Unfortunately, telling these mice apart from each other is rather difficult. They are like sparrows and finches in that they’re small, brown, and quick. Hopefully, you’ve learned something interesting about these five species.
